Rapid In-Vivo Propagation of Curcums Using Stem Cuttings grown in Different Media

The In Vivo propagation of Curcums (Z. spectabile) using stem cutting grown in different media was investigated at Central Mindanao University, Musuan, Bukidnon from June 15 to September 30, 2005. The study was conducted in a 3 x 4 factorial arrangement in a Completely Randomized Design replicate thrice with five samples per replicate. Three stem cutting sections: basal, middle and tip served as factor A and five growing media: garden soil, sand plus rice hulls, garden soil plus sand, and rice hulls plus sand as factor B.

Basidiomycetous Mycelial Isolates as Compost Inoculant

Screening of basidiomycetous mycelial isolates as compost inoculant. One practical way to dispose wastes is thru bio-conversion into composts using basidiomycetous fungi which degrade the wastes into simpler compounds and bring back the nutrients to the soil. Seven different basidiomycetous mycelial isolates were obtained from mushroom fruiting bodies gathered from VISCA Forest Reserve and screened for their decomposition ability as compost inoculant of agricultural waste substrates namely: rice hull, rice straw, banana leaves, leaf litter and sawdust.

Plants Extracts as Control Agents of Braconid

Selected Plants Extracts as Control Agents of Braconid sp. Corcyra cephalonica Stn. is used as a fastidious host in the production of Trichogramma sp. It is a stored grain pest with the common name rice grain moth which can be found in corn/rice mills. It is easy to handle and can be mass produced in the laboratory. The mass production of Trichogramma sp., a biological control agent of lepidopterous pests is dependent on the abundance of Corcyra cephalonica Stn.

Spirulina platensis: Potential Biosorbent for Lead

Heavy metal contamination is one of the problems encountered by industrialized countries due to its harmful implications. At present, biosorption, a biological method in removing heavy metal ions, is deemed as an inexpensive and effective alternative to physico-chemical methods of separation in treating wastewater contaminated with heavy metal ions. This study Spirulina platensis: Potential Biosorbent for Lead aimed to prove the effectiveness of Spirulina platensis in absorbing lead ions from simulated wastewater. S. platensis and lead acetate were obtained from UPLB. Four separate 90 ml lead solutions, each containing 50 ppm of lead, were prepared and inoculated with 10 ml of S. platensis.
